Oceanside Glasstile Tessera series 1x1 White non iridescent.

Yes, it is a 1x1 glass tile. I cannot confirm it is by Oceanside because it was sourced by the interior designer, but Oceanside makes a similar product!

I'm using a bright white glass tile in my kitchen, 1x3 stacked. Any suggestions on grout color? I want very little, if any, contrast between grout and tile, but have been told not to use a true white grout. Thanks.
